Our solid mount kit is ideal for track, race, and extreme performance street vehicles. Does not harm ride quality but may add a bit of noise.
By mounting the differential using solid mounts, you can eliminate the damage causing torquing and twisting between the diff and subframe, as such, the VAC Aluminum Differential Mount Kit is designed to unitize the differential housing and the subframe on the E9X M3.
The result: improved driver feel and feedback, enhanced reliability, and elimination of sub-frame tearing and chassis damage that can occur when these mounts fail during hard track driving!
VAC Tech Tip:
We have already seen damage occur from this failure using street tires. If you drive your E9X M3 on the track, we can recommend this upgrade.
